Logic
Mastery
Amazing, Amusing, Amorous, Delicious, Delightful, Edifying,
Strengthening Elixir.
It eases work & learning difficulties Makes the hard easier. Opens eyes.
Leads to greater precision.
in reading and
writing
Do not leave here without it - Logic mastery will develops critical thinking, improve reading and writing, and give a firmer base for work and studies at many levels. Good luck.
After logic, (a) continue reading Three Skills for Algebra, chapters 8 to 14 and do so alongside site area on solving linear2007 Equations ; or (b) see this calculus starter lesson and Volume 3, Why Slopes & More Math, chapters 2 to 6;

What may be learnt and when depends on how skills and concepts are developed. Making the hard easier and clearer will allow earlier & richer development of skills and concepts.
George Orwell: Is it nonsense for arts and disciplines based on and respected for carefully mastery of rules and methods, alone and combined, to face education reforms based on the supposition that mastery of rules and methods is not a sign of intelligence. Would you like to rewrite 1984 to include that angle?
Try the Twiddla Whiteboard. In principle, it allows to people to draw and chat together online on a copy of this webpage or a clean sheet. The chat may be via text or audio. Visit twiddla.com to set up whiteboards to work with the webpage of your choice.
Precalculus sites mathsisfun & purplemath are visually more appealling than this one. Do not go.
For online automated help in senior high school maths & calculus, visit quickmath.com For Automatic Calculus and Algebra Help with derivatives, integrals, graphs, linear equations, matrix algebra, visit calc101.com With overlap, each site quickmath & calc101offers a different range of services, some free, some not, all based on webmathematica. Good luck.

Fallacies and Non-Rational Persuasion
Fallacious Appeals
Misdirected Appeals:
Appeal to Authority
| Lateral Thinking Bottleneck |
||
 |
Put a coin in a bottle and then stop the opening with a cork. How can you
get the coin out of the bottle without pulling out the cork or breaking
the bottle?
|
|
 |
Push the cork into the bottle, and shake the coin out. |
| Lateral Thinking Coast to Coast |
||
|
Train A and train B are crossing the country, from coast to coast, over
3,000 miles of railroad track. Train A is going from east to west at 80
miles per hour, and Train B is going from west to east at 90 miles per
hour. Which train will be closer to the west coast when they meet? (Hint:
You don’t have to do any math to get the answer. Just use your head!)
|
|
|
When the trains meet, they will be at exactly the same point. Therefore,
they will each be the same distance from the west coast. |

| Lateral Thinking Digging Dirt |
||
|
How much dirt is in a round hole that is 9 feet deep with a diameter of 3
feet? (Hint: You don’t have to do any math to get the answer. Just use
your head!)
|
|
|
None. You make a hole by digging out the dirt, so the hole is empty. |
